PHOTO-NEGATIVE BATH-DISH.

SPECIFICATION forming part of Letters Patent No. 422,143, dated February 25, 1890.

Application filed August 16,1889.

To LZZ whom it may concern/.-

Be it known, that I, JOHN R. MOELLER, of Grand Island, in the county of Hall and State of Nebraska, have invented a new and Improved Photo Negative Bath Dish, of which the following is a full, clear, and exact description.

This invention relates to dishes of the class employed in the treatment of photo-negatives, the objects of the invent-ion being to support a number of negatives in a .single dish in a manner such that they will not bear against each other, and also in a manner such that the lower edgesl of the negatives will be held above the sediment that is deposited in the bath.

To the ends above named the invention consists in the construction hereinafter more fully described, and specifically pointed out in the claim.

Reference. is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views. f

Figure 1 is a plan view of my improved photo-negative bath-dish. Fig. 2 isa longitudinal sectional view on line 1r of Fig. 1, and Fig. 3 isa cross-sectional view on line y y of Fig. 2. y

In the drawings, 10 represents a dish, preierably of porcelain or earthernware, and formed with a series of inwardly-extending ribs or flanges a a a a', the ribs or flanges .extending inward from each end Wall of the dish. Across the bottom of the end walls there are formed ledges 5l1, adapted to support the lower edges of the negatives.

In the treatment of negatives they are Serial No. 321,006'. (No model.)

placed so that their ends rest between the ribs at either end of the dish, their lower edges resting upon the ledges 11, thus holding the negatives apart, as represented-in Figs. 1 and 3. Negatives of a length suiiicient to reach frein ledge to ledge would ordinarily be placed as represented in Fig. 2; but in order that shorter negatives may be treated in the dish I form side walls of the dish with inwardly-extending flanges b b b b, and between said flanges I insert a corrugated partition 12, which, when the plates are adjusted, as indicated by dotted lines in Fig. 1, serves to hold the said plates from touching.

If desired, the dish may be provided with handles 13, as illustrated. Now, although I have represented only two inwardly-extending ribs at each side of the dish, I desire it to be understood that any number of such* JOHN R. MOELLER.
